The removal or extraction of teeth destroys the ideal esthetics and occlusion, which was the base of orthodontic treatment plans. Edward Hartley Angle and his followers were not supporters of extraction due to this reason. Extreme dental or maxillary protrusion leading to facial deformities could be corrected by dental extraction was supported by Calvin Case who was a strong opponent of the Angle., for mainly analyzing the frequency of use of orthodontic extractions after evaluating the changes in the use of extraction in past years. The frequency of extractions was examined in relation to gender and Angle’s malocclusion classification. \u0000Materials and Method: This is a retrospective observational study. It was conducted in Orthodontics Department of Nishtar Institute of Dentistry, from 2015 to 2020. In this study records from 1032 patients who reported to orthodontic department in Nishtar institute of dentistry Multan for fixed orthodontic treatment were taken. For data registration SPSS 20 (IBM Chicago Illinois) was used. Frequency of extractions with regards to gender, skeletal pattern and types of extraction pattern was determined. In order to assess the association among variables Chi square test was applied and a P value of less than 0.05 was considered as significant. \u0000Result: In respect of extraction group, 222 (41.3%) were males and 316 (58.7%) were female and whereas in nonextraction group, 83 (16.8%) were males and 411 (83.2%) were females. The difference was statistically significant (p<0.001). The frequency of extraction in reference to Angle’s classification was analyzed, and no significant difference was found (p=0.992). Frequency of extraction was highest in class-II division-I malocclusion, and the lowest frequency of orthodontic tooth extraction was seen in class-II division-II malocclusion. \u0000Conclusion: It can be concluded from the results of our study that females had higher frequency of extractions as compared to males. Similarly, class II malocclusion patients had highest frequency while lowest frequency was in Class I malocclusions.","PeriodicalId":31197,"journal":{"name":"Orthodontic Journal of Nepal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44443564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study is to assess the prevalence of malocclusion in school going children of Parsa district, Nepal, and to compare the same with previous study. \u0000Materials and Method: The sample consisted of 250 males and 210 females (total of 460 subjects) aged between 6 to 17 years. Subjects without any previous orthodontic treatment and with no dental anomalies were included in this study. Census sampling was done for the patient visiting orthodontic from November 2018 to March 2019. Classification of malocclusion was based on Angle’s classification of malocclusion. Collected data were entered in Microsoft Excel 2007 and converted into Statistical Package for Social Science (SPSS) Version 11.5 for statistical analysis. For descriptive statistics, percentage and proportion, were calculated, also tabular presentation were performed. For inferential statistics, Chi square test were used for intergroup comparison. \u0000Result: School going children of Parsa district, Nepal suggests 50.47% female and 45.6% of male exhibits Angle’s Class I malocclusion, 29.04% female and 30% male exhibits class II pattern, 11.4% female and 12.0% male exhibits class III pattern. The other findings reported in the study were, the occurrence of crowding of teeth more in males whereas the occurrence of spacing is more in females. \u0000Conclusion: Majority of the subjects in the study had Class I malocclusion. Only 9.04% female and 12.4% of male showed normal class I occlusion. The occurrence of crowding of teeth more in males whereas the occurrence of spacing is more in females.

Role of mandibular third molar in lower anterior crowding remains a topic of controvery over a period of century. The objective of this study was to assess whether there is any correlation between presence of mandibular third molar position and lower anterior crowding. \u0000Materials and Method: On the basis of third molar position one hundred and six sample of pretreatment orthodontic patients aged between 17 to 38 years were divided into erupted, erupting and agenesis group.

Enamel surface changes, prior to bonding, were studied using a stereomicroscope (Olympus SZX7) and an optical microscope. 20 extracted premolars were arranged in 2 arch forms with 5 teeth in each quadrant, after which impression of the arches with rubber base impression material was made. These impressions were then sent to the laboratory for the fabrication of a customized lingual appliance. The remaining 20 premolars were divided into 2 arches, each arch having 10 extracted premolars divided into 4 sets, 1st to test customized brackets bonded with chemical cure resin without sandblasting, 2nd to test customized brackets with dual cure resin without sandblasting, 3rd to test conventional brackets with chemical sure resin with and without sandblasting and 4th to test conventional brackets bonded with dual cure resin with and without sandblasting. The post debonding photographs were analyzed using a standardized grid and Surface Roughness Index. \u0000Result: Thus, enamel defects are likely to be caused post debonding despite of using any combination. However, the surface roughness index has been shown to be highest post debonding in cases where customized brackets have been bonded using dual cure resin along with sandblasting. \u0000Conclusion: While a clinician may opt for a material like Rely X U200 to bond lingual appliances in order to have a better clinical management of the appliance, but he would have to keep the possibility of irreversible damage to enamel post debonding.","PeriodicalId":31197,"journal":{"name":"Orthodontic Journal of Nepal","volume":"10 1","pages":"14-20"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43952514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increase in public awareness and availability of orthodontic specialty services have led to increasing number of orthodontic patients in specialty clinics and hospitals. The objective of this study is to examine the pattern of malocclusion in the patients visiting medical and dental teaching hospitals and dental clinics and to measure the different Angle’s classification of malocclusion with discrepancies in all three planes. \u0000Materials and Method: Three hundred seventeen acceptable study casts were selected from 403 case records of orthodontic patients who visited the different hospitals and private clinics of Province 2, Nepal. A standard guidance of Angle’s classification was used to classify the cases and casts were measured to record the data. Different Angle’s classification of malocclusion with discrepancies in all three planes was studied. Descriptive statistics (frequency, percentage, mean and SD) and inferential statistics (chi square and fisher exact test) was used to find out the association between occlusal traits and demographic variables. \u0000Result: According to the Angle’s classification of malocclusion, most of the patient’s cast 65.9% were of class I, followed by class II 31.8%, class III 5.3% occlusion pattern.
